Danger
Mandatory
• When using switchgear for the inverter, it must be installed in a cabinet.
Failure to do so can lead to risk of electric shock and can result in death or serious injury.
Be Grounded
• Connect earth cables securely.
Failure to do so can lead to risk of electric shock or fire in case of a failure or short-circuit or electric
leak.

Note 1: Sizes of the wires connected to the input terminals R/L1, S/L2 and T/L3 and the output terminals U/T1,
V/T2 and W/T3 when the length of each wire does not exceed 30m.
Note 2: For the control circuit, use shielded wires 0.75 mm

or more in diameter.
Note 3: For grounding, use a cable with a size equal to or larger than the above.
Note 4: The wire sizes specified in the above table apply to HIV wires (cupper wires shielded with an insulator
Note 4: The wire sizes specified in the above table apply to HIV wires (cupper wires shielded with an insulator
with a maximum allowable temperature of 75°C) used at an ambient temperature of 40°C or less.
Note 5: If there is a need to bring the inverter into UL compliance, use wires specified in Chapter 9.
